At 361m in length, it’s longer than both the Eiffel Tower and Burj Al Arab. Spanning 16 decks, it weighs 227,000 gross registered tonnes and has the capacity to house 5,497 guests at double occupancy; In short, Royal Caribbean’s latest Oasis-Class ship Harmony of the Seas, is a ship of monstrous proportions; more of a floating city than a luxury cruise liner.

Setting sail on its inaugural sea voyage this June on a western Mediterranean itinerary, Harmony of the Seas is not only the biggest ship in the world, it’s also one of the most luxurious.  This nautical marvel boasts spectacular on-board features, many being firsts-at-sea, something award-winning Royal Caribbean International is renowned for. Perhaps the most anticipated feature being The Ultimate Abyss, which at 150 feet above sea level is the tallest slide on the high seas and will challenge the nerve of even the most daring of guests. In addition, The Perfect Storm trio of water slides twist and turn over Central Park® some 10 decks below and will thrill water-babies of all ages.

Keeping you high up in the air with a birds-eye view is the first zip lines at sea, where you can partake in an exhilarating ride across an open-air atrium suspended above the breathtaking neighbourhood of the Boardwalk with its family friendly activities, eateries and shops. Here, the young (and the young-at-heart) can ride on the full-size carousel which has been handcrafted just for Royal Caribbean and is another fantastic first, before replenishing at one of the many cafes and restaurants found here which include international brands.

The adventure, however, does not stop there, for you can try your hand at a spot of rock-climbing on two 43ft tall climbing walls which flank the open-air AquaTheater, home to a full spectrum of awe-inducing aquatic aerial displays, before perfecting your balance on the FlowRider® surf simulators.

Children are treated to days with their favourite DreamWorks® characters; from breakfasts in the main dining room to special ‘meet and greet’ experiences during the day and the renowned Adventure Ocean® Youth Program also offers those aged between three and eleven years an entertaining line-up of activities and games throughout the duration of their stay.

If you prefer your holidays a little bit less adrenalin filled then rest assured, Harmony of the Seas offers relaxation in droves too. Sit back and soak up the sunshine around one of four pools or inside the adults-only solarium with its serene whirlpools. Pamper yourself at the advanced VitalitySM Spa  with it fitness centre and extensive number of treatment rooms – the largest collection at sea.

As the sun sets, the ship comes alive. Take a stroll hand-in-hand through Central Park® with its bustling al fresco piazza before stopping in one of the many signature restaurants such as Chops Grille, for a bite to eat. On board Royal Caribbean you can even enjoy restaurants featuring celebrity chef partnerships such as Jamie’s Italian by Jamie Oliver.

After dining, visit the futuristic Bionic Bar, a technology-forward venue complete with two robotic bartenders that shake, muddle and mix a wide variety of drinks made to order. In fact, Harmony of the Seas is the first Oasis-class ship to feature this photo-worthy outlet, so don’t forget your camera!

That’s not to say that the evening ends there, for the Entertainment Place is the very beating heart of the ship after dark.  Setting the stage for entertainment ensembles, Harmony of the Seas pulls back the curtain on Broadway’s hit musical Grease in the spectacular Royal Theatre. And just when you thought you’d seen it all, prepare to be dazzled by the theatrical grace of world-class skaters in one of two extraordinary ice shows.

Following a day of exploring the world, its exotic cuisine and interesting cultures, there is nothing better than returning to the comfort of your private stateroom. Harmony of the Seas features 2,747 beautifully appointed staterooms that offer luxurious and comfortable accommodation, many with spectacular views out towards to the sea, and with four main categories there is something for every preference.
